It can read and write images in a variety of <a href="www/formats.html">formats</a> (over 100) including <a href="www/motion-picture.html">DPX</a>, <a href="www/high-dynamic-range.html">EXR</a>, GIF, JPEG, JPEG-2000, PDF, PNG, Postscript, SVG, and TIFF. Use ImageMagick to resize, flip, mirror, rotate, distort, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves.</p>
<p>The functionality of ImageMagick is typically utilized from the command line or you can use the features from programs written in your favorite language. Choose from these interfaces: <a href="www/api.html#ada">G2F</a> (Ada), <a href="www/api.html#c">MagickCore</a> (C), <a href="www/api.html#c">MagickWand</a> (C), <a href="www/api.html#ch">ChMagick</a> (Ch), <a href="www/api.html#com_">ImageMagickObject</a> (COM+), <a href="www/api.html#c__">Magick++</a> (C++), <a href="www/api.html#java">JMagick</a> (Java), <a href="www/api.html#lisp">L-Magick</a> (Lisp), <a href="www/api.html#lua">Lua</a>, <a href="www/api.html#neko">NMagick</a> (Neko/haXe), <a href="www/api.html#dot-net">Magick.NET</a> (.NET), <a href="www/api.html#pascal">PascalMagick</a> (Pascal), <a href="www/api.html#perl">PerlMagick</a> (Perl), <a href="www/api.html#php">MagickWand for PHP</a> (PHP), <a href="www/api.html#php">IMagick</a> (PHP), <a href="www/api.html#python">PythonMagick</a> (Python), <a href="www/api.html#ruby">RMagick</a> (Ruby), or <a href="www/api.html#tcl">TclMagick</a> (Tcl/TK). With a language interface, use ImageMagick to modify or create images dynamically and <em>automagically</em>.</p>
